Isikhokelo esibanzi kwiimfuno zokulinganisa izibambo ze-bimetal kunye ne-digital thermometers

Kwindawo yokulinganisa ubushushu, ukulinganisa i-thermometers yinkqubo ebalulekileyo eqinisekisa ukuchaneka kunye nokuthembeka kokufundwa kweqondo lokushisa.Ukuba usebenzisa i-bimetal stemmed okanyeithemometha yedijithali, imfuneko yokulungelelaniswa ibaluleke kakhulu ukugcina imigangatho yokuchaneka okufunekayo kumashishini ahlukeneyo kunye nezicelo. Kule ntetho icacisayo, siphengulula kwiingqwalasela ezinxunguphalisayo ezijikeleze ulungelelwaniso lwezi zixhobo ze-thermometric, zikhanyisela xa kwaye kutheni ezo nkqubo zokulinganisa zibalulekile.

I-Bimetal stemmed thermometers, ebonakaliswe ngokwakhiwa kwayo eyomeleleyo kunye noyilo lomatshini, ixhomekeke kumgaqo wokwandiswa kwe-thermal ukulinganisa utshintsho lobushushu. Ngaphakathi kwekhoyili ye-helical yomgca we-bimetallic, eyenziwe ngeentsimbi ezimbini ezingafaniyo kunye ne-coefficients eyahlukeneyo yokwandiswa kwe-thermal, ukuhluka kweqondo lokushisa kubangela ukwandiswa okungafaniyo, okubangela ukuphambuka okunokulinganiswa kwesiqu. Ngelixa i-bimetal stemmed thermometers ibonelela ngoburhabaxa kunye nokomelela, ubume babo bomatshini bufuna uhlengahlengiso lwamaxesha ngamaxesha ukubuyisela ukuphambuka okunokubakho okanye ukutenxa kokuchaneka okufunekayo.

Ukulinganisa i-bimetal stemmed thermometers kufuneka kwenziwe phantsi kwezi meko zilandelayo:

• IShedyuli yoLondolozo lwarhoqo:

Ukugcina ukuthotyelwa kwemigangatho yolawulo kunye neeprothokholi zokuqinisekisa umgangatho, i-bimetal stemmed thermometers kufuneka ijongwe kwi-calibration ngamaxesha achazwe kwangaphambili, ngokuqhelekileyo amiselwa yimigaqo yoshishino okanye imigaqo-nkqubo yombutho. Le ndlela esebenzayo inciphisa umngcipheko wokungachaneki kwaye iqinisekisa ukuthembeka kwemilinganiselo yokushisa kwiinkqubo ezibalulekileyo okanye izicelo.

• Iinguquko ezibalulekileyo zokusiNgqongileyo:

Ukuvezwa kumaqondo obushushu agqithisileyo, uxinzelelo kumatshini, okanye indawo enomhlwa inokuchaphazela ukulinganisa kwe-bimetal stemmed thermometer ngokuhamba kwexesha. Ke ngoko, uhlengahlengiso lunokuqinisekiswa emva kotshintsho olubalulekileyo lwemo engqongileyo okanye iimeko zokusebenza ezinokubeka esichengeni ukuchaneka kwesixhobo.

• Emva koMothuko weMechanical okanye iMpembelelo:

Iithemometha ezineziqu zeBimetal zisesichengeni sokukhukuliseka okubangelwa kukothuka komatshini okanye impembelelo yomzimba. Ngenxa yoko, nawuphi na umzekelo wokuphatha kakubi okanye umonakalo ongazinzanga kwisixhobo kufuneka ukhuthaze uhlengahlengiso olukhawulezileyo ukuze kulungiswe nakuphi na ukutenxa kwisimo esilinganisiweyo.

Okuchasene,ithemometha yedijithali, abahlulwe ngokujikeleza kwabo nge-elektroniki kunye nomboniso wedijithali, banikezela ngokuchaneka okungenakulinganiswa kunye nokuguquguquka kumlinganiselo wobushushu. I-teknoloji ye-sensor ye-sensor kunye ne-algorithms elawulwa yi-microprocessors, i-thermometers yedijithali ibonelela ngexesha langempela, ukufundwa kobushushu obuchanekileyo kunye nokungenelela okuncinci komsebenzisi. Ngaphandle kozinzo kunye nokuthembeka kwazo, iithemometha zedijithali azikhuselekanga kwiimfuno zokulinganisa, nangona zineengcamango ezahlukileyo xa kuthelekiswa noomatshini babo.

Ulungelelwaniso lwethemometha yedijithali luqinisekisiwe phantsi kwezi meko zilandelayo:

• Ulungelelwaniso lwasefektri:

Iithemometha zeDijithali zidla ngokulinganiswa kumzi-mveliso ukuze zihlangabezane nemigangatho yokuchaneka echaziweyo phambi kokusasazwa. Nangona kunjalo, izinto ezinje ngezothutho, iimeko zokugcina, okanye ukusetyenziswa komsebenzi kunokufuna uhlengahlengiso ukuze kuqinisekiswe kwaye kugcinwe ukuchaneka kwesixhobo ekuhambeni kwexesha.

• Ukuqinisekiswa kwamaxesha athile:

Ngelixa iithemometha zedijithali zibonisa uzinzo olukhulu kunye nokuphinda-phinda xa kuthelekiswa neethemomitha ezine-bimetal stemmed, kucetyiswa ukuba kuqinisekiswe ukulinganisa ngamaxesha athile ukuze kuqinisekiswe ukuchaneka okuqhubekayo kunye nokuthembeka. Oku kunokubandakanya uthelekiso nemigangatho yereferensi okanye isixhobo sohlengahlengiso esinokulandelelwa ngokwemigangatho yesizwe okanye yamazwe ngamazwe.

• Ukuqhuba okanye ukutenxa:

Ithemometha yedijithali inokuba nokukhukuliseka okanye ukutenxa kwisimo esilinganisiweyo ngenxa yezinto ezifana nokuguga kwecandelo, ukuphazamiseka kwe-elektroniki, okanye iimpembelelo zokusingqongileyo. Nakuphi na ukungangqinelani okuphawulweyo phakathi kofundo lwethemometha yedijithali kunye nemilinganiselo eyaziwayo yereferensi kufuneka ikhuthaze uhlengahlengiso ukubuyisela ukuchaneka.

Ukuqukumbela, ulungelelwaniso lwazo zombini i-bimetal zibangelwa kwayeithemometha yedijithalingumba osisiseko wokuthembeka komlinganiselo wobushushu, oxhasa ukuthembeka kunye nokuchaneka kokufundwa kobushushu kwizicelo ezahlukeneyo. Ngokuqonda iimfuno ezithile zokulinganisa kunye neemeko ezisebenzayo kuhlobo ngalunye lwe-thermometer, oogqirha banokuqinisekisa ukuthotyelwa kwemigangatho yokulawula, iiprothokholi zokuqinisekisa umgangatho, kunye neendlela ezifanelekileyo kwi-metrology yobushushu. Nokuba usebenzisa i-bimetal stemmed okanye ithemometha yedijithali, ukufuna ukuchaneka kuhlala kubaluleke kakhulu, ukuqhuba uphuculo oluqhubekayo kunye nokugqwesa kwiindlela zokulinganisa ubushushu.
